vnstat json does not have an id field

[jeffbrissette]

More an FYI, my version of vnstat does not dump the interface name as an id , rather it is name.

my version is
vnStat 2.6

I don't think this branch works well with vnstat 2.x yet.

I have a version here that works for me:

Feel free to try it

I actually got it work no problem with a few tweaks to the code for name instead id and changing the date format to something more ISO. Personally, I might write something for myself. The version of vnstat I have uses an SQLite db, which is pretty easy for PHP to read and do queries against.
